Sirenidae is a small family of amphibians that is found in the Southern United States and Mexico. The family is split into two living genera – Dwarf Sirens (Pseduobranchus) and Siren. There are other genera in the fossil record.

The main characteristic of the family is lack of hind legs. They also have long, eel-like bodies with gills. They eat both plants and animals.

Dwarf Sirens (Pseudobranchus)differ from Sirens on how many toes they have on each foot. Dwarf Sirens (Pseudobranchus) have three toes on each foot than four on each foot such as Siren.
